Specification of Letters Patent No. 11,923, dated November 14, 1854. i

To all whom it may concern:

Be it known that I, LEVI B. BALL, of the town of Putnam, in the countyofMuskingum and State of Ohio, have invented a new and useful Improvementin Smut-Machines; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, in which- Figure l is a perspective view, Fig. 2, an endview, and Fig. 3 also an end View of a different form.

My invention consists in employing in the concaves of smut machines woodand iron slats or any other hard and soft substances arrangedalternately in the manner and for the purposes to be presentlydescribed.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. I construct theheads of my concave of cast-iron plates, separating at the center ofeach head. VVit-h the lower half of said head-plates I connect the legson which the machine stands, atthe top of the same a cross-bar, I, onwhich the inner-cylinder or beatershaft journals rest in a suitable box.On the inner side of the head-plates and at the verge are fillets, runaround far enough apart to receive the ends of the strips ofwrought-iron and wood which form the concave; on the same surface arealso placed fillets for the reception of the intermediate plate, E,which extends the whole length of the machine and may be curved tocorrespond with the concave as shown in Fig. 3, or bent to an angle inthe direction of its length as shown in Fig. 2.

The dimensions of the strips of iron and wood used in the concave may bevaried according to the size of the machine. For a machine of mediumsize,--say, four or five feet in length and twenty inches in diameter,Iuse strips of iron one inch wide and one eighth of an inch thick; thestrips of wood are of the same width but one fourth thinner. Butthatpart of the concave which is adjacent to the opening F in the sideinstead of being formed of the usual alternate strips of wood and iron,consists simply of boards lined on the inside with sheet iron, theseboards entering the fillets in the same manner as the strips andconstituting about one-third of the concave. That part of thehead-plates which is opposite the opening F is furnished with flanges toreceive bars of wood. In the ends of the boards and bars are placedbolts which passing through the head'plates and being fastened, securethe frame-work of the machine in its proper position. The frame of themachine being thus set up, I proceed to complete the concave, of whichthe boards adjacent to the opening form about one third, with the stripsof wood and iron, or with other hard and soft material alternatelyarranged. When the lower half of the concave is completed to the uppersurface of the bar which is bolted to the lower half of each head plate,the strips composing it are held to their places by extending a strip onthe surface of the bar and screwing itdown. The

strips composing the upper half of the concave are secured in the samemanner.

The inner cylinder represented by G in the Figs. 2 and 3 is made in theusual manner, with cast-iron heads or arms and wrought-iron shafts. Onthe extremities of the arms are bolted bars, three inches wide, onefourth of an inch thick, more or less according to the size of themachine, these bars running parallel with the shaft: the number of barswill ordinarily be about twelve, But the arms on that end of thecylinder, which is toward the head of the machine, are placed each fromone half to three fourths of an inch forward of the corresponding arm onthe other end, in order to give the bars in revolving the effectof aspiral, in conveying the grain from one end of the machine to the other.This cylinder is to be made of such size that when placed in theconcave, there shall be a space of one inch between it and the concaveat the ends, and also, the same space between the circumference in whichthe bars of the inner cylinder revolve, and the concave :or, the innercylinder is to be two inches less in diameter than the concave, andthere is to be one inch space at each end between it and the head-platesof the concave. The shaftof this inner cylinder extends beyond thehead-plate of the concave sufficiently to afford space for theattachment of a screen and pulley. The screen consists of a framesimilar to a small window frame over which is extended ordinary screenwire sufiiciently fine to prevent the escape of the grain. The frame issufliciently large to extend beyond the opening in the head of theconcave and sufliciently deep to throw the Wire beyond the box in whichthe shaft revolves, and at the top and. bottom is bolted 'to theheadplates. The wire is nicely fitted to the shaft, where the latterpasses through it.

The grain is let in at the top of the concave at one end, as at K, (Fig;2), and is discharged belowthe side opening at the other end of themachine, as at L. To the opening, F, which extends the entire length ofthe concave is attached a trunk, ascending perpendicularly six feet moreor less,

and then returning down again and connect 'The strength of the draft ofthis fan is, regulated ing with a common suction fan;

fan-by means of which they will be carried away leaving the pure grainto pass out at its appropriate opening.
